Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a controller box that is housed and fixed inside a case and insulated from the outside.

Conventional technology Generally, when mass producing this type of controller box, as shown in FIG.
After the power cord 4 having a power cord 4 is directly soldered to the print base 12, it is placed on the case 10 and the case 11 is assembled. For these controller boxes, in order to improve productivity in mass production, the case 710 is placed on a pallet, the print base 12 to which the power cord 4 is soldered is placed on the case 10 by an automatic machine, and the case 11 is also placed by an automatic machine. Concurs with Case 10.

Problems to be Solved by the Invention: However, in the production process of such a controller box, since the power cord 4 is soldered to the print base 12, the center of gravity of the print base 12 becomes unstable, and many Print base 1 with electronic components of
2, the automatic machine is placed on print base 1.
Only two sides can be supported.

As a result, it becomes difficult for the automatic machine to accurately place the print base 12 on the case 10 on the pallet, and the case 1o and case 11 are deposited with the print base 12 incompletely placed on the case 10. Case 10
There is a problem that the print base 12 may be pinched between the case 11 and the print base 12 may be destroyed, or the power cord 4 may be pinched and broken.

For this reason, in the past, it was necessary for the operator to accurately re-place the print base 12 placed on the case 10 each time, which significantly worsened the work efficiency, and the power cord was soldered to the print base 12. Due to the weight of 4, the center of gravity of the remounted print base 12 becomes unstable,
There was a problem in that it was very difficult to increase the required positioning accuracy with respect to the case 10.・The present invention solves these conventional problems, and makes it possible to produce controller boxes with a simple configuration, without causing damage to the printed base or disconnection of the power cord during production. Moreover, it provides an excellent controller box that can improve production efficiency.

Means to Solve the Problem The controller box of the present invention is formed by depositing two cases, and when depositing the two cases, the contact pin receiving part inside the case, Before the contact pins of the print base are deposited, the guide pins of the first case and the guide pin receiving portions of the second case are deposited.

Function: By connecting the power cord to the contact pin receiver fixed to the second case, the controller box of the present invention allows the automatic machine to accurately locate the print base with a stable center of gravity without the power cord connected. can support
In addition, since the guide pin of the first case can place the print base along the notch 9 of the print base which has a peripheral tail notch, the positioning accuracy between the first case and the print base can be significantly improved. can be improved,
This eliminates the destruction of the print base and the disconnection of the power cord that occur when depositing the first and second cases with the print base incompletely placed on the first case.

Embodiment Hereinafter, a controller box according to an embodiment of the present invention will be explained with reference to the drawings and FIGS. 1 to 4.

First, the contact pin receiving part 6 to which the power cord 4 is connected is fixed to the second case 2. In this embodiment, the pin tightening method is used as a method for fixing the contact pin receiving portion. The force of the first case 1 is that the pin 8 guides the print base 3 along the notch on the periphery of the print base 3 and places it on the first case. 3 and the contact pin receiving portion in the second case 2 can be positioned with high precision.

Next, the singing match in the first case 1 and the second case 2 will be explained. The guide pin 8 of the first case 1 is formed higher than the contact pin 7 of the printed base 3 placed thereon, and the guide pin receiving portion 9 of the second case 2
is formed higher than the pin receiving portion fixed to the second case 2.

As a result, when depositing the first case 1 and the second case 2, the guide pin 8 is first guided by the guide pin receiving part 9, and the difference in the singing position of the first case 1 and the second case 2 is caused. Deposit will be made while reducing the amount. On the other hand, since the lengths of the contact bin 7 and the contact pin receiving part 6 are lower than the heights of the guide bin 8 and the guide pin receiving part 9, no deposit is made, and the guide pin 8 and the guide pin receiving part 9 At the same time that the discrepancy between the singing positions of case 1 and case 2 is resolved, contact pin 7 and contact pin 6
will pay a deposit.

As mentioned above, for the controller box formed by depositing two cases, after eliminating the misalignment of the cases during singing, the contact pins of the printed base 3 are positioned with high precision. 7 and the contact pin receiving part 6 can be assembled together.

Therefore, the operator does not have to re-place the print pace 3 placed on the first case by the automatic machine each time, and work efficiency can be significantly improved.

As described above, the controller box of the present invention has the contact pin receiving part connected to the power cord fixed to one of the two cases, and the guide pin of the case fixed to the guide of the printed base in the other case. It can also be used as a pin, and when placing the print paste on the case and joining the two cases, place the guide pin and guide pin receiving part of the two cases before the contact pin and contact pin receiving part of the print paste. This eliminates any misalignment between the print base and the case when they are combined, and the misalignment of the singing positions between the cases, so even when using an automatic machine to make a deposit, the print base will not be destroyed or the power cord will be disconnected. etc., and is of great help in improving the quality of the controller box itself, improving yield, and improving workability.
